Abstract

EL DISPOSITIVO SEGUN LA INVENCION COMPRENDE UN TUBO BUZO (1) ADAPTADO PARA PENETRAR EN EL ORIFICIO SUPERIOR DE ADAPTACION (7) DE UN CARTER (6) DE TRANSFORMADOR O DE INDUCTANCIA INMERSO EN UN DIELECTRICO LIQUIDO. EL TUBO BUZO (1) ESTA SUJETO POR UNA PLACA BASE (3) REMATADA POR UNA PARTE INTERMEDIA TUBULAR TRANSPARENTE (17) Y POR UN ALOJAMIENTO SUPERIOR (15). UN DETECTOR DE POSICION (45) DE LAMINA FLEXIBLE, ALOJADO EN EL TUBO BUZO (1), ES SENSIBLE A LA POSICION DE UN FLOTADOR (22) QUE LLEVA AL MENOS UN IMAN (23) Y DESLIZANTE SOBRE EL TUBO BUZO (1) EN LA PARTE INTERMEDIA TUBULAR TRANSPARENTE (17). EN POSICION NORMAL, EL IMAN (23) ESTA ALREDEDOR DEL DETECTOR (45) EN ESTADO DE TRABAJO. UNOS DETECTORES DE TEMPERATURA (25, 26, 27) ESTAN ALOJADOS EN LA PARTE INFERIOR (2) DEL TUBO BUZO (1). UN DETECTOR DE PRESION (28) RECIBE LA PRESION EN EL INTERIOR DEL CARTER (6). LOS DETECTORES DE PRESION, DE POSICION Y DE TEMPERATURA CONSTITUYEN CONTACTOS SECOS QUE NO NECESITAN NINGUNA ALIMENTACION EXTERIOR. ELDISPOSITIVO PERMITE ASI CONTROLAR EL CORTE DE ALIMENTACION DE UN TRANSFORMADOR O DE UNA INDUCTANCIA EN CASO DE ELEVACION ANORMAL DE TEMPERATURA O DE PRESION O DE BAJADA DE NIVEL DE DIELECTRICO LIQUIDO.
